    um.. 3+ body problem for an "asteroid" game comes to mind, realistic damping due to wind resistance, the same but weather, realistic looking vehicle suspension, stinger-missile simulation, aerodynamic simulation, realistic looking water/weather..

    Pretty much anywhere that the underlying equation is more complicated than a simple spherical potential.

    Sure you *could* hard code it in, but if the analytical result is a function like exp(-x^2)cos(x), you're going to have include quite a few higher order terms to evaluate it to any precision, and you lose any advantage you had if the ODE could've been solved with a few simple multiplication/additions.

    If all you care about is, "given state f({x},t=n) what is state f({x},t=n+1)" a numerical ODE solver is pretty much ideal for that.

  4. Re:Subsidies as a cure for "economic inefficiency" on Open Source R&D Tax Credit? · · Score: 1

    You've made a very important assumption. The assumption you're making is that the breakdown goes like this:

    government removes $1.20 from the economy through taxation

    $0.20 lost as "waste heat" somehow
    $1.00 spent on economically useful projects

    $1.00 + $.20 = $1.20, and everyone's happy.

    The real problem is that by definition, a governments activities contrary to an efficient market. If they weren't, those activities would already be taken care of by said market. The social merits of those activities are irrelevant to this discussion. The simple fact is that government action hurts the economy regardless its other benefits.

    I believe the real equation goes more like this:

    Government directs $2.00 of the economy's output/feedstock.
    $1.00 of this is accounted for on-the-books through taxation
    $0.80 of this is accounted for between-the-lines through debt service
    $0.20 of this is accounted for by inflation due to out-and-out printing-too-much-money

    The distinction between debt and moneyprinting is a bit fuzzy, and plenty of accounting tricks are used to hide the various means. Accounting tricks used by accountants paid out of the $2.00 btw. However, redirected wealth recognized as debt does serve to reduce inflationary pressure. Also, counterfeiters remove wealth via the third option as well. However, it could not be said that their activities have any socially redeeming value whatsoever, and are a separate entity from government and irrelevant to discussing government's effects.

    so, some conclusions: Government spending removes wealth from the economy regardless of how it is accounted for simply by redirecting efforts. Governments do not need to tax anything at all. They could simply print all the money they need and allow inflation to take care of the value removed from the economy. Therefore, the tax plan serves two purposes:

    1) reduce inflation by keeping the money supply constant
    2) direct the lost wealth at specific individuals/ classes of individuals to avoid accountability.

  9. That's exactly what you wanna do on NVIDIA Launches New SLI Physics Technology · · Score: 2, Insightful

    For a game, the best way to solve ODEs is numerically. Since you don't need the precision of the exact solution, the solutions are considerably simpler computationally once you've linearized them. Doing RK4 on the fly is precisely the best solution to the problem. Well, depending on the stiffness.. but you can always fall back on plain ol' trapezoid rule if you just wanna know, "what does the thing do until it hits the ground" to enough precision to be pretty.

    solving a linearized ODE is just plain ol' ordinary matrix math, very parallelizeable and a lot less computationally expensive than breaking up a transcendental function into piecewise conitinuous steps and calculating the result every time.

    6) Writing my congressman doesn't help me play a movie tonight, tomorrow, next week, or probably even this year. People want immediate solutions. Let's keep working on the long term, but I'd like to watch my movies legally now, thanks very much. Of course, I have a DVD player, and a decent TV, so I don't really care whether my computer can play them.

    Y'know, we bitch about this one quite a bit, but the fact is that software decoders must be legal on some level, or they wouldn't exist for windows either. And the licensing fees can't be too outrageous, because many popular DVDs come with software decoder "upgrades." So what we need to do is start some kind of foundation and get people to donate to it (or sell something related people would want to buy) and purchase a license.

    In fact, I wonder if I haven't missed the boat and someone's already doing this right now...

    Sure it might be a less principled action than getting sufficiently large groups of people to set aside their militant apathy* and get congress to vote the "right" way, but there are are so many other more important things they could be spending their energy on if they'd bother to care about anything at all that it seems a bit selfish even.

    *a term I'm sure I wasn't the first to coin, which is the only way I can describe the reaction of a friend of mine when I tried to engage in a little political discussion. I'd never before heard the phrase, "I don't care" uttered with so much passion.

    IIRC, the PBJ patent is for a specific varient of the pbj sandwich in which BOTH sides are peanunt-buttered as a barrier between the bread and the jelly.
